![]() The first, and most obvious one, is that it sounds like you are trying to edit a movie that is almost an hour-long in After Effects. It has been a long time since I worked with a development team designing compression algorithms but we did a lot of really weird stuff to video frames in the early days. I don't know for sure if that is what is going on, but it is not an unreasonable explanation. Locking the frame rate That could account for the hour-long video running out of frames before the video is over. If nothing is changing in the frame for 5 or 6 frames you might have a single frame that is 5 or 6 frames long. When you lock a variable frame rate movie to a constant frame rate and there is no audio track you might be dropping a bunch of frames. Thanks in advance for your time and assistance! Can anyone more knowledgeable than I please tell how to overcome this problem? I have a feeling it's not overly difficult, but I haven't been able to find anything via internet searches or searches here on the forum. It's only when I bring it into AE that it's getting cropped. The video plays fine in preview, QuickTime, or any other app - all 52 minutes. They change the playback speed of the video, obviously, but nothing I know to try recovers the full length of the video. I have toyed with the footage frame rate and I've toyed with the composition frame rate neither make any difference. I'm losing a half hour of my video and I can't figure out why. The problem is that once I do this, no matter what number I change it to (I started with 52 but have tried many different numbers since), it cuts my video off at about the 22 minute mark. Well when I bring the 52 minute video (mp4) into AE (CS5), it informs me that the frame rate is 51.7126 FPS and I get the typical 17 18 incompatibility warning that I've encountered many times in the past and have fixed simply by changing the frame rate to a whole number. So I've been doing some screen captures of myself working on my iPad Pro to post to YouTube but after a recent update it reset the capture function to the default setting of having the microphone in the off position, so I rewatched my own video and recorded a voiceover, thinking I'd simply bring the file into after effects and throw the audio on there and render a new version to throw up on youtube.
